V6 auxilary belt replacement

[john adam]

Hello greetings from a very warm new Zealand.
I am in the process of replacing the auxiliary belt on our 2.5 V6 with 270,000 kms on the clock. The idler bearing had seized causing the belt to overheat, shredding itself to pieces and damaging the pulley on the tensioner.
The work involved for what should be a simple maintenance job is horrendous. Easy if the engine is removed. Sounds a simple job according to the Haynes manual, yeh right!
I have ordered the various parts (including the tensioner and idler) which are due to arrive from the UK shortly.
Looking at the tensioner it is only the removable pulley wheel which needs replacing rather than having to buy the whole assembly. However, it would appear that you cannot buy it on its own.
I cannot find a "how to" on the forum. Any suggestions from the experts would be appreciated.

John,

Another member told me that the idler wheel is also used as the pulley on the tensioner. However, the entire tensioner assembly is only marginally more expensive so it hardly seems worth the hassle to attempt to remove the pulley.
